The narrow scale of steel sash profiles and the large sash sizes used in today's architecture demand better locking methods. Europe leads the world in the development of multi-point locking in order to meet their stringent energy requirements.
We continue to evolve our steel products with the use of multi-point locking systems in our windows and doors. When possible to use, multi-point locking helps achieve the best security and weather tightness in our line of large products.
Electric locking is always the problem child. Typically electric locks or electric strikes limit you to a single locking point. The convenience of the electric locking is shadowed by the loss in efficiency of the weather seal system with a single locking point. Although Europe has developed a number of multi-point door locks, these do not work well in narrow sightline steel products because of the bulkiness of their electric multi-point design.
Swing Door Locking
Pushing down on the door lever will open the door for normal use. In the closed position, pulling up on the lever will engage all locking points. Next, turn thumb or key and lock the door. When you turn again and push down on lever this will release all locking points.
On a door pair the multi-point is installed in the active door and will strike into the inactive door. The secondary, or inactive door, will lock into the frame at the top and the sill at the bottom of the door. The inactive door locks are engaged using individual flip levers located on the edge of the door.
